HS-565BRH_12 Datasheet, PDF (1/9 Pages) Intersil Corporation – Radiation Hardened High Speed, Monolithic Digital-to-Analog Converter

Radiation Hardened High Speed, Monolithic
Digital-to-Analog Converter
HS-565BRH, HS-565BEH
The HS-565BRH, HS-565BEH are fast, radiation hardened
12-bit current output, digital-to-analog converters. This part
replaces the HS-565ARH, which is no longer available. The
monolithic chips include a precision voltage reference,
thin-film R-2R ladder, reference control amplifier and twelve
high-speed bipolar current switches.
The Intersil Dielectric Isolation process provides latch-up free
operation while minimizing stray capacitance and leakage
currents, to produce an excellent combination of speed and
accuracy. Also, ground currents are minimized to produce a
low and constant current through the ground terminal, which
reduces error due to code-dependent ground currents.
HS-565BRH, HS-565BEH die are laser trimmed for a
maximum integral nonlinearity error of ±0.25 LSB at +25°C. In
addition, the low noise buried zener reference is trimmed both
for absolute value and minimum temperature coefficient.
Specifications for Rad Hard QML devices are controlled by the
Defense Supply Center in Columbus (DSCC). The SMD
numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96755. A “hot-link” is provided on our
website for downloading.
